SPECIFICATION forming part of Letters Patent No. 564,459, dated July 21,1896.

Application filed April 30, 1896. Serial No. 589,754. (No model.)

To all whom it may concern:

Be it known that I, EDWIN J. STRONG, a citizen of the United States ofAmerica, residing at Plover, in the county of Pocahontas and State ofIowa, have invented certain new and useful Improvements in Wagon-BodyLifters; and I do hereby declare the following to be a full, clear, andeXact description of the invention, such as Will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in wagon-body lifters, the objectof the same being to provide an apparatus for removing a wagon-body fromits bed or runninggear and support said body in an elevated position, sothat it can be readily replaced when desired.

The invention consists in the construction and combination of the parts,as will be hereinafter fully set forth, and particularly pointed out inthe claims.

In the accompanying drawings, forming part of this specification, Figurel is a side View showing the parts of the apparatus in their relativepositions prior to the raising of the wagon-body. Fig. 2 is a side Viewshowing the position of the parts in the act of raising the wagon-body,and Fig. 3 is a plan view of the apparatus.

In carrying out my invention I firmly secure in the ground, or in a barnor shed, two sets of posts or standards a, a', and a2, the said sets ofposts or standards being located a suitable distance from each other toallow the passage of a wagon between them.

To the posts a and o. on each side of the passage-Way are pivoted barsor levers A and A', the upper ends of which are connected tolongitudinal beams B B, to which they are pivoted by pins h, two of saidpivot-pins projecting beyond the outer edges of the longitudinal beams,so as to be engaged by notched bars C C, which arepivoted at their lowerends to the posts a2. The longitudinal beams B also carry guides h',which prevent lateral movement of the notched bars C and thereby insuretheir engagement withthe pins h.

D designates a pawl which is pivoted to the longitudinal beams B by theends of the laterally-extended members d d thereof engaging loops B',which are passed vertically through said beams and arey connected attheir lower ends by a plate, and between these platesA and the beams Bare interposed helical springs b2, said springs serving to permit amovement of the loops B should undue strain come upon the pawl. It willbe noted that by this arrangement the pawl can be readily connected toand disconnected from the longitudinal beams B, which is necessary inthe operation of the apparatus, as the space between the longitudinalbeams should be free to permit the passage of the Wagn.

When the apparatus is in position to raise the wagon-body, the parts arearranged in the position shown in Fig. l of the drawings, with thelongitudinal beams B resting upon the upper ends of the posts a', thenotched bars C resting against the pins b, and the pawl D removed. Nowafter the wagon is moved into position between the longitudinal beamsthe ends of the pawl D are passed under the loops B and the free end ofsaid pawl caused to engage the rear part of the runninggear, cross-barsc c being placed under the wagonbody and rest upon the longitudinalbeams B. l/Vhen the parts are so arranged, the wagon is drawn forwardand the longitudinal beams B will be raised through the intervention ofthe pawl D and carry the wagon-body with them until said wagon-bodymoves free of the standards to which it is connected, the notched bars Oacting to hold the parts in their elevated position. .When therunning-gear of the wagon is being drawn forward from under the body,the pawl D will swing clear of the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In an apparatus for elevating wagonbodies, the combination, of a pairof longitudinal beams, levers connected at their upper ends to thelongitudinal beams, apawl carried by the longitudinal beams, and notchedbars which engage said longitudinal beams to hold them in an elevatedposition, sub- IOO stantially as shown and for the purpose set forth.

2. The combination of the longitudinal beams B B, bars A and A' pivotedat their lower ends to suitable supports andat their upper ends to saidlongitudinal beams, a pawl removably connected to the longitudinal beamsand adapted to engage the running* gear of the Wagon, and means forsupporting the longitudinal beams in an elevated position, substantiallyas shown and described.

3. In an apparatus for lifting andsupporting Wagon-bodies, theCombination, of longi* tudinal beams B B, bars A and A' pivoted to saidbeams and to suitable supports, loops B passed vertically through thelongitudinal
